Patent number: 8084340Abstract: A method of manufacturing a semiconductor device whereby, even in cases where ions are implanted into a shallow region of a semiconductor substrate when a deep well is formed, the influence of the ions on a MOSFET can be removed, thereby eliminating the need for increasing the chip area. A photoresist with a thickness matching the wavelength of exposure light is formed over the semiconductor substrate and then is exposed to the exposure light to form a photoresist pattern with an opening corresponding to a region for forming a first well. Subsequently, using the photoresist pattern as a mask, ions are implanted to form the first well, and after the photoresist pattern is removed, an epitaxial layer is grown over the semiconductor substrate. Consequently, the deep well is virtually located deeper in level than at the time of the ion implantation by an amount corresponding to the thickness of the epitaxial layer.Type: GrantFiled: October 3, 2006Date of Patent: December 27, 2011Assignee: Fujitsu Semiconductor LimitedInventor: Satoshi Nakai

Patent number: 7223098Abstract: An ignition unit promotes the efficiency of assembly because connections on the high voltage output side and the ground side are completed by a single operation, when an ignition electrode part and a main unit are connected together directly. A guide rail of the main unit is insertion-engaged into a slit between clamp pieces of a bracket so that the main unit is mounted onto the bracket. With the insertion engagement, a high voltage output terminal receives therein a high voltage input terminal of a spark plug supported by the bracket, a plate terminal which is a part of the bracket is driven into a ground-side connection terminal, and a convex portion of a projected piece is engaged into an engagement hole, for positioning and slipping-off prevention.Type: GrantFiled: August 4, 2004Date of Patent: May 29, 2007Assignee: Noritz CorporationInventors: Hideya Suyama, Atsushi Yoshimoto, Kozo Uehara, Masaaki Kumon, Satoshi Nakai, Kazuya Kawauchi, Takuji Saiki, Shingo Kimura, Naomi Tanaka

Patent number: 6900088Abstract: First and second gate electrodes are formed on first and second regions of a semiconductor substrate. Second conductivity type impurities are implanted into the second region to form first impurity diffusion regions. Spacer films are formed on the side surfaces of the first and second gate electrodes. Second conductivity type impurities are implanted into the first and second regions to form second impurity diffusion regions. After the spacer films are removed, second conductivity type impurities are implanted into the first region to form third impurity diffusion regions. The third activation process is performed so that the gradient of impurity concentration distribution around the third impurity diffusion region becomes steeper than the gradient of impurity concentration distribution around the first impurity diffusion region.Type: GrantFiled: February 28, 2002Date of Patent: May 31, 2005Assignee: Fujitsu LimitedInventors: Ryota Nanjo, Shinji Sugatani, Satoshi Nakai
